Just shipped a knobbyknife to uk. Total cost with import duty came to £65. I thought it was a little expensive for what it looked like,untill I used it .What a great tool! I have re-trimmed the tyres on my sons bike ,my bike and also six rear tyres and three fronts .All of which would have been thrown away but are now as good as new .I cant recomend this enough .Especially in the current economic climate.Also the saving on the environment , not throwing away tyres with 99% of the rubber still on them.
